The group, now performing as a trio consisting of G-Dragon, Taeyang, and Daesung, is scheduled to release a new digital single titled ‘BiiiG’ on August 19, 2026. The title is a play on the group’s name, with the three ‘i’s symbolizing the current three-member lineup. YG Entertainment stated that ‘BiiiG’ is a track that “most clearly represents the group’s current musical identity” as they celebrate two decades in the industry. This marks their first release in over four years following the 2022 single ‘Still Life.’ To commemorate two decades in the industry, a media art project titled ‘Cosmos’ will be held in Seoul, featuring multimedia installations, a drone light show, and fireworks at Yeouido Park. Following these celebrations, the group will launch the ‘BIGBANG 2026-2027 WORLD TOUR XX: COSMOS.’ The tour is set to begin at Goyang Stadium in South Korea from August 21 to 23, 2026, and will eventually comprise 33 performances across 19 cities in North America, Europe, Oceania, and Asia, including scheduled stops in locations such as Manila, Malaysia, and Vietnam. ## Timeline ### 2026-08-09: BIGBANG announces 20th anniversary single ‘BiiiG’ and world tour K-pop legends BIGBANG will release a new digital single, ‘BiiiG’, on August 19, 2026, to celebrate their 20th anniversary, followed by a global ‘XX: COSMOS’ world tour. 16 sources. https://clstr.news/cluster/bigbang-to-release-new-single-biiig-and-launch-20th-anniversary-world-tour ### 2026-07-22: BIGBANG to hold free 20th‑anniversary fan event on Seoul’s Han River BIGBANG will mark its 20th anniversary with a free fan event on Seoul’s Han River on 19 August, featuring DJ sets, video retrospectives, multimedia art, a drone show and fireworks, ahead of a world tour. 4 sources. https://clstr.news/cluster/bigbang-to-hold-free-20thanniversary-fan-event-on-seouls-han-river --- Cite as: BIGBANG 20th anniversary celebrations and world tour.
